Of course, maybe I'm the only person to have picked up on this... but by putting the analogue pedals in the digital domain, it wouldn't take much to make every old analogue pedal, midi enabled. Want to recall a pedal with different settings? No problem! The main challenge would be making the pedals look presentable as opposed to a hacked electronics project.
The ability to sweep an analogue pot under MIDI control... hmm. I wonder if anybody has done this in any capacity? I'm going to have a google...
Hmm, maybe I should get my embedded programming hat on again.
